SCALE to set the vertical scale at 1-2-5 step, i.e. 1 mV/div, 2 mV/div, 5 mV/div,
10 mV/div...10 V/div.

Vertical Expansion

When changing the vertical scale of the analog channel by rotating the Vertical
SCALE knob, you can select to expand or compress the waveform around the
"Center" or "GND" (Ground). By default, "GND" is selected under Expand.
Press 1 → More, then press Expand continuously to select "Center" or "GND".
Center: when the vertical scale is changed, the waveform will be expanded or
⚫
compressed around the screen center.
GND: when the vertical scale is changed, the waveform will be expanded or
⚫
compressed around the signal ground level position.

To Adjust the Vertical Offset

Vertical offset indicates the offset of the signal ground level position of the waveform
from the screen center in the vertical direction. Its unit is consistent with the
currently selected amplitude unit (refer to "Amplitude Unit"). When adjusting the
vertical offset, the waveforms of the corresponding channel moves up and down.
The vertical offset information (as shown in the following figure) in the channel
status label at the bottom of the screen will change accordingly.
The adjustable range of the vertical offset is related to the current input impedance,
probe ratio, and vertical scale.
When CH1 is turned on, you can adjust the vertical offset with the following four
methods:
Rotate Vertical
⚫
offset within the adjustable range. Rotate this knob clockwise to increase the
vertical offset, and rotate it counterclockwise to reduce the vertical offset.
Pressing down the knob can quickly reset the vertical offset (set the vertical
offset to 0).
Menu setting: Press 1 → More → Offset, and then the numeric keypad is
⚫
displayed. Input the offset value with the numeric keypad.
Enable the touch screen, and then adjust the vertical offset with the drag
⚫
gesture. For details, refer to the "Drag" section.
Enable the touch screen function, and tap the channel status label at the bottom
